Hi 
I'm connected through L2CAP and what should I send now to connect RFCOMM. I know that it should be SABM and I should wait for UA but how to do this?
Where is a command to do this and how it looks like. RFCOMM packets are insight L2CAP as a command?
Can anyone tell me what it's like and howto make a command to send SABM and make rfcomm connection?

Regards 

Maciej

what kernel are you using? Are you using udev? Is the /dev/rfcommX
device node present? What version of the bluez-utils are installed?

Regards

Marcel

Hi Amine,

this reminds me of a race that a normal user can't release a previous
created RFCOMM TTY if no device node is found and so the connection
still exists, but nobody can use it. The fix for the rfcomm utility is
already in CVS and the kernel update will be part of my big easter
update.

Regards

Marcel
